NOAA's Paleoclimatology archive provides a tree-ring width chronology from the Timber Gap Lower site in California. The data covers 713 years, from 750 to 37 BCE, for climate reconstruction studies. It was published by NOAA National Centers for Environmental Information in 1987.
Use Cases
- Reconstructing past temperature or precipitation anomalies in California using the tree-ring width time-series.
- Calibrating regional climate models by comparing the 713-year tree-ring chronology with other proxy records.
- Analyzing long-term climate trends and extreme events (e.g., droughts) in the western United States from the annual-resolution ring width data.
- Studying ecological responses to historical climate shifts using the dated tree-ring sequence.
Strengths
- Covers a 713-year time period (750 to 37 BCE), providing a long-term climate proxy.
- Data is curated and archived by NOAA's authoritative World Data Service for Paleoclimatology.
Limitations
- Data is from a single site (Timber Gap Lower, CA532), limiting spatial representativeness.
- Last metadata update was in 1987, potentially lacking modern methodological annotations.
- Sample size (number of trees/cores) and replication statistics are unknown from the description.
